|
conservative
|
|
|
dispersive
|
|
|
semiconservative
|
Explanation:
Detailed explanation-1: -According to the semiconservative model, after one round of replication, every new DNA double helix would be a hybrid that consisted of one strand of old DNA bound to one strand of newly synthesized DNA.
Detailed explanation-2: -After Watson and Crick proposed the double helix model of DNA, three models for DNA replication were proposed: conservative, semiconservative and dispersive. But Meselson and Stahl proved semiconservative is actual the mode of DNA replication .
Detailed explanation-3: -Watson and Crick outlined a model for DNA replication, later called semi-conservative replication. According to Watson and Crick, in preparation for DNA replication, the two strands of DNA first unwound and separated.
